Abstract

Opposite and equal currents are forced on first (7) and second (8) bus lines. A first source (5) of voltage supplies voltage. A second source (6) of voltage/current controls the opposite and equal currents and generates data bits on the bus lines. Negative-positive-negative transistors (3,4) link to a minus pole on the emitter side. Triggered by the second source of voltage/current, positive-negative-positive transistors (1,2) generate two equal collector currents, one (I1) for the first bus line and a second (IT1) for an input for a current mirror circuit.
